Concept:A mango is a drupe fruit. Its edible part is the middle layer of the fruit wall called the mesocarp.
Explanation:The mango fruit has three layers: epicarp (skin), mesocarp (flesh), and endocarp (hard stone around the seed).
The epicarp is the outer skin, not eaten.
The mesocarp is the thick, juicy, sweet part that we eat.
The endocarp is the hard inner layer covering the seed, not eaten.
Thus, the edible part is the mesocarp.
Answer:B. Mesocarp
